It is a really disappointing, frustrating issue. I've even had the SMC fail and had to reset it due to this issue, and it affects my work several times a month. When I switch inputs on my DisplayPort / HDMI display to view my PC desktop, it often crashes - Especially with the DP → HDMI setup/monitor, but also with the play DP cable (this is across two different test displays apart from the Ultrafine).If the laptop goes to sleep, I cross my fingers that it won't break. Other times, opening the lid crashes things.

I close the MacBook lid to save a bit of performance since I only use the two desktop displays, but sometimes that crashes things.
It helped a bit to stop using the $300 Belkin dock I bought from apple for the Ultrafine, so it is only serving the third display - but issues abound.

I have had just terrible trouble with crashes as well on my brand new MacBook Pro this year, but connecting a LG Ultrafine and a Display Port (or HDMI via a DisplayPort → HDMI cable) display results in an unpredictable, crash-prone environment.
